Muscle pain is associated with decreased motor unit discharge rate during constant force contractions. As discharge rate is a determinant of force, other adaptations in strategy must explain force maintenance during pain. Our aim was to determine whether motor unit recruitment strategies are altered during pain to maintain force despite reduced discharge rate. Motor unit discharge behavior was ...

Biological rates in small animals are usually higher than those in large animals, yet the maximal rate of action potential (spike) generation in sensory neurons encoding rate functions is similar in all animals, due to the conserved genetics of voltage-gated ion channels. Therefore, sensory signals that vary at rates approaching maximal spike generation rate, as might occur in animals of dimini...

BACKGROUND This study evaluated changes in motor unit (MU) firing rates in young and older adults during exercise training. METHODS Vastus lateralis MU discharge rates were measured in 8 young and 7 older adults. Each participant performed isometric knee extension contractions at 10%, 50%, and 100% of maximal voluntary contraction or effort (MVC) on two separate occasions. Participants then c...

INTRODUCTION The diabetes hospitalization rate for the region along the U.S. side of the U.S.-Mexico border is unknown, a situation that could limit the success of the Healthy Border 2010 program. To remedy this problem, we analyzed and compared hospital discharge data for Arizona, California, and Texas for the year 2000 and calculated the diabetes hospitalization rates. METHODS We obtained h...

Design: We used a queuing theory model to simulate 3 different potential solutions to decrease the delay from patient identification to connection with discharge services. Measurements: The measures included average rate at which patients were being connected to the post discharge heart failure services program, average number of patients in line, and average patient waiting time. Results: Usin...

objective: non-compliance is one of the major problems in treatment of patients with schizophrenia. it is also the most significant risk factor for relapse and re-hospitalization. previous studies showed that 25-70% of all patients with schizophrenia have negative attitudes to drugs. therefore, the present study aimed to identify the relationship between drug attitude and discharge and the rate...

there are several factors that lead to early return of patients to the medical centers. these could be due to latent illnesses, misdiagnosis or even inadequate medical care due to staff being worn out. determining the mentioned factors could help decrease the rate of readmission, restore patient's confidence in health centers and decrease the cost of medical care. chi lung wu et al. in 2010 sou...

Objective: Predict patient-specific vitals deemed medically acceptable for discharge from a pediatric intensive care unit (ICU). Design: The means of each patient’s heart rate, systolic and diastolic blood pressure measurements between their medical and physical discharge from the ICU were computed as a proxy for their physiologically acceptable state space (PASS) for successful ICU discharge. ...

25 The underlying neurophysiology of postural control of the lower back in humans is 26 poorly understood. We have characterized motor unit (MU) discharge activity in the 27 deep lumbar multifidus (LM) muscle in 9 healthy subjects (20–40 years, 3 females). 28 Bilateral fine wire electrodes were implanted at L4 spinal level using ultrasound 29 guidance. EMG was recorded during spontaneous sittin...

introduction: discharge against medical advice (dama) can be an important indicator of patient dissatisfaction. this study examined the reasons for the dama in shafa hospital (kerman, iran). methods: this was a descriptive cross-sectional study within august 2010 to march 2011 on patients in this hospital. over 9295 inpatients were discharged, 483 had dama and were assigned 190 contacts and out...
